Selec XT546 Multifunction Digital Timer – Dual LED Display, 48 × 48 mm

Description

Product Overview
The Selec XT546 Multifunction Timer is a digital timer relay built for controlling time-based operations in industrial equipment and electrical control panels. Its dual LED display shows the timer setting and timing information, while the front keypad allows users to configure the required time and operating mode.
The XT546 supports four functions: ON-delay, interval, cyclic ON-first, and cyclic OFF-first. Its multiple time ranges provide flexibility for applications that require short delays or longer timed sequences.
